7955937d31 Refactor Parser to make it usable on a background thread. 
- Background Parsers cannot get the following data from Isolate (pass it to the
ctor instead): stack limit (background Parsers need a different stack limit),
UnicodeCache (background parsers need a separate UnicodeCache), hash seed
(Parser cannot access the Heap to get it). The Parser::Parse API won't change.

- Make the internalization phase (where Parser interacts with the heap) more
explicit. Previously, Parser was interacting with the heap here and there.

- Move HandleSourceURLComments out of DoParseProgram, so that background parsing
can use DoParseProgram too.

7117cae25e Make FrameStates recursive (to be used for inlining). 
- Changes FrameState node to require a 5th input
  (use undefined as sentinel).
- Adds outer_state pointer to FrameStateDescriptor.
- Instruction selection dumps dependencies of FrameState chain into the instruction.
- Code generator builds the translation for rec. FrameStates.
  (will require further integration tests)

496697df4e Add MachineSignature, which is an encapsulation of the machine types for parameters and return values in a graph. 
This utility will be used to simplify Linkage and fix representation inference
to work with graphs where parameters and return values are something other
than tagged. It will also make testing representation inference a lot
easier, since we can then exactly nail down the machine types of parameters
and returns.

This CL also adds c-signature.h, which demonstrates how to convert C function
signatures into MachineSignatures. The CSignatures will be used in tests to
make it easier and simpler to codegen tests.

e7817a9e54 Remove dependency from generic lowering on compilation info for determining strictness and builtins. 
This makes the graphs compositional for inlining (i.e. we can now inline a strict function into a non-strict function, or vice versa).

1) Store strict mode as parameter in StoreNamed/StoreProperty.

71fbe7d4ec Ensure that JSProxy::Fix gives the generated JSObject map a constructor 
All JSObjects in V8 either have a map()->constructor() field or are
JSFunctions. JSProxy::Fix, however, was not enforcing this, and
Object.observe's use of JSObject::GetCreationContext() exposed this.

Note that this is not Object.observe-specific: the API call
v8::Object::CreationContext() also would have revealed this bug.

This patch chooses Object as a reasonable constructor to put on the
newly-fixed object's map. Note that this has no effect on the "constructor"
property in JS. In doing so, I've also tightened up the code underlying
JSProxy::Fix to only support JSObject and JSFunction as possible output
types.
